Dad was asked to travel to the location and take a picture; he doesn't have a GPS device, but the building is clearly visible on the google satellite view. He couldn't reach the exact spot, but could take a picture of it from the road, as well as a couple of others to prove he's at the right corner. I guess this counts as not-quite-reaches, as the actual coords (so far as I can tell) lie in the field, and that's not publicly accessible.
